#Windows Routing and Remote Access Service (RRAS)

Out-of-bounds read in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to disclose information over a network.

Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.

**According to the CVSS metric, the attack vector is network (AV:N), user interaction is required (UI:R), and privileges required are none (PR:N). What does that mean for this vulnerability?** Exploitation of this vulnerability requires an unauthorized attacker to wait for a user to initiate a connection to a malicious server that the attacker has set up prior to the user connecting.

**According to the CVSS metric, the attack vector is network (AV:N), user interaction is required (UI:R), and privileges required are none (PR:N).

Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.

**How could an attacker exploit this vulnerability?** An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server via the Routing and Remote Access Service (RRAS) Snap-in. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** In a web-based attack scenario, an attacker could host a website or server that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.
